White-Hot Metal. The most striking Middletown project is SNAP-50, a lightweight nuclear-power reactor designed to operate in space. Incorporating technical know-how gained on the airplane-engine project, this SNAP (for Systems for Nuclear Auxiliary Power) contains liquid lithium and gaseous potassium, tricky fluids that would drive most engine designers to seek liquid solace. Molten lithium is frightening stuff; it corrodes almost anything, and bursts into flame on contact with oxygen. Gaseous potassium, while not quite so bad, is hot and explosive...
...gross annual volume heads the international list of contractors. Among other things, Kiewit has built the Air Force's base in Thule, Greenland, a giant radio telescope in West Virginia, a Titan missile base in California, Minuteman bases in North and South Dakota, a $1.2 billion AEC gaseous diffusion uranium processing plant in Ohio...
...less than 1½ in.) in diameter. The tube slips painlessly through the insensitive brain to the deep-lying thalamus. The tube's outer layer is a vacuum insulator; the innermost bore carries liquid nitrogen supplied at -196° C.; the middle layer is for warmed and gaseous nitrogen to escape...
...more of their military purchasing from American firms to help the U.S.'s gold drain. "You need dollars. Here is what will get you dollars,'' said Lavaud, handing U.S. officers a list of things that France would like to buy. It included equipment for a gaseous diffusion plant to make enriched uranium, plans for nuclear submarines, propulsion and guidance gear for rocket missiles...
...swallow was the realization that if Beech-ing succeeds in adapting to modern needs and techniques a 50,000-mile network designed for the 1880s, scores of branch lines and hundreds of its 7,000 stations will disappear. The last of the beloved "puffing billies" will yield to gaseous diesels or electric locomotives, and the aromatic privacy of the old first-class passenger compartment will give way to open, air-conditioned cars with central aisles, airliner seats and Muzak...
